v4.0.0

[4.0.0] - 2023-08-17

Added

• Flavor-aware colors: pen, brush and paper

  • By default, all geometries utilize new flavor-aware colors.
  • Theme geom parameter allows redefinition of "geom colors": theme(geom=element_geom(pen, brush,paper)).

  See: example notebook.

• stat_summary() :
  example notebook.

• stat_summary_bin() :
  example notebook.

• stat_ecdf() :
  example notebook.

• geom_function() :
  example notebook.

• theme_void() [#830] :
  example notebook.

• "sum" statistic [#821]:
  example notebook.

• "boxplot_outlier" statistic: example notebook.

• Support for variadic line width and/or color in geom_line() and geom_path() [#313].

  example notebook.

• In tooltip customization API:
  disable_splitting() function [LPK-189].

  example notebook.

• In geom_pie():

  • stroke and color aesthetics - the width and color of pie sector arcs.
  • stroke_side parameter - which arcs to show (inner, outer, both).
  • spacer_width and spacer_color parameters - lines between sectors.

  See: example notebook.

  • size_unit parameter : example notebook.

Changed

• The default qualitative color palette is now Color Brewer "Set1" (was "Set2")

• Geometries default colors are now flavor-dependent: example notebook.

• Geometries default size/line-width is now slightly bigger.

• Point size is adjusted to match the width of a line of the same "size".

• [BREAKING] geom_pie() no longer supports parameter stroke_color.

• [BREAKING] geom_boxplot() no longer support parameter sampling.

• [BREAKING] geom_pointrange(): size aesthetic shouldn't affect line width [#751]:

  linewidth aesthetic is used for line width, size - for mid-point size only.

• geom_boxplot(): size and stroke parameters now affect outlier shapes.

• [BREAKING, only affects users of Lets-Plot Kotlin API]
  The entire project has undergone package refactoring.
  As a result of package names changed, Lets-Plot v4.0.0 is partially incompatible
  with Lets-Plot Kotlin API versions 4.4.1 and earlier.

Fixed

• ggsave() doesn't save geom_raster() layer to a file [#778].
• ggsave(): saving geomImshow() to SVG produces fuzzy picture [LPK-188].
• ggsave(): saving geomImshow() to raster format produces fuzzy picture.
• geom_crossbar() aesthetics take middle argument instead of y [#804].
• geom_boxplot() doesn't apply alpha to outliers [#754].
• geom_boxplot() outliers do not show tooltips.
• geom_step() no tooltips.
• geom_step(): toggle the behavior of the direction parameter when the orientation is changed.
• geom_livemap(): memory leak when re-run cells without reloading a page.
• geom_ribbon(): not all tooltips are shown on a multi-layer plot [#847].
• Bug in empty plot: IndexOutOfBoundsException [#194].
• Weird tooltip/legend in case of extremely long value [#315].
• panning on interactive map should be more responsive [#336].
• Offline mode doesn't work with manylinux wheels [#808].
